The Spiro Mounds Archeological Center is the only prehistoric Native American archeological site in Oklahoma open to the public. One of the most important American Indian sites in the nation, the Spiro Mounds are world renowned because of the incredible amount of art and artifacts dug from the Craig Mound, the site’s only burial mound. Home to rich cultural resources, the Spiro Mounds were created and used by the Caddoan speaking Indians between 850 and 1450 AD.

The sign is made out of a proprietary material called FOTERA Structural Concrete suitable for outdoors it is unique because it is made without the need for metal dividers separating the color fields and still presenting a crisp and subtle gradation of color inherent in photographs depicted in concrete.
